PGA Tour rookie Shawn Stefani never came close to making a bogey until his final hole Thursday in the Tampa Bay Championship in Palm Harbor, Fla.

Stefani rolled in a par putt from just under 5 feet to complete a 6-under 65 and take a two-shot lead over Brian Harman.

"Kind of fought through a couple of bad shots coming in -- or not so great shots -- and managed to get balls up-and-down and make a few putts," said Stefani, 31, who placed 16th on the Web.com Tour money list in 2012. "So all in all, it was a great day."

Harris English finished on the 18th and like Stefani, hit into a bunker. Except he three-putted from 40 feet for a double bogey and a 68, tied with Brendan Steele and Tag Ridings.

Defending champion Luke Donald opened with a 70 despite being 4 under with four holes to play.

John Daly shot a 72.

LPGA Tour: Ai Miyazato took the LPGA Founders Cup lead on a hot afternoon in Phoenix, playing a late four-hole stretch in 5 under for a 9-under 63.

Returning from a whiplash injury sustained in a five-vehicle crash after a tournament in Thailand three weeks ago, Miyazato birdied the par-3 14th, sank a 20-foot eagle putt on the par-5 15th and added birdies on the par-4 16th and par-3 17th for a two-shot lead over Jee Young Lee.
